This notice disposes of public comments received by the Federal Aviation Administration (FAA) in response to a Federal Register notice published on February 22, 2013, requesting comments on a potential restructuring of the rotorcraft airworthiness standards of Title 14 of the Code of Federal Regulations (14 CFR) parts 27 (normal category rotorcraft) and 29 (transport category rotorcraft). Specifically, the agency sought comments on the necessity of updates to parts 27 and 29, including whether to change the existing weight- and seat-based applicability standards for normal and transport rotorcraft. Based on the comments received, the FAA is terminating this docket. Commenters indicated a substantial interest in revising or restructuring the certification standards for parts 27 and 29, and the FAA's Rotorcraft Directorate will begin establishing the appropriate forums to involve interested parties.
